Activator of phosphatase enzyme is:
Correct answer: C. Zn2+
- A. Mn2+
- B. Mg2+
- C. Zn2+
- D. None of these
Explanation
Mn2+, Co2+, Ni2+ with an activating effect, Zn2+ with an inhibitory effect. They all bind to the enzyme at the same site and also induce the supposed conformational change. However, Zn2+ is able to produce interactions, perhaps with Pi which is one of the products of hydrolysis, which might explain its inhibitory effect.

About Biological Molecules
The chapter covers water's polarity and biological roles, carbohydrates, lipids, proteins and nucleic acids, including their monomers, bonds, structures and functions. It also distinguishes RNA from DNA and explains conjugated molecules such as glycoproteins, glycolipids and nucleoproteins, which combine organic molecules with a non-protein component.
